Ferrocene Derivatives Enable Ultrasensitive Perovskite Photodetectors with Enhanced Reverse Bias Stability

open access: yesAdvanced Functional Materials, EarlyView.
Novel ferrocene derivatives (e.g., FcPhc2) are used as an ultrathin layer hole‐blocking layer, reducing hole injection from the Ag contact. This results in an ultralow noise spectral density of 1.2 × 10−14 A Hz−1/2, and a high specific detectivity of 8.1 × 1012 Jones at −0.5 V.

Analysis of 3D-printed metal for rapid-prototyped reflective terahertz optics [PDF]

open access: yes, 2016
We explore the potential of 3D metal printing to realize complex conductive terahertz devices. Factors impacting performance such as printing resolution, surface roughness, oxidation, and material loss are investigated via analytical, numerical, and ...

530 BREAST FEEDING, GROWTH AND MORBIDITY [PDF]

open access: yesPediatric Research, 1981
The effect of exclusive breast feeding in the first few months of life on physical growth was studied prospectively in a group of 36 full-term healthy newborns. Growth failure was not observed in any infant until after the third month of life. The average growth curve for the entire group was between the 25th and 50th percentile at the end of the study

Understanding and Optimizing Li Substitution in P2‐Type Sodium Layered Oxides for Sodium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
This work explores Li‐substituted P2 layered oxides for Na‐ion batteries by crystallographic and electrochemical studies. The effect of lithium on superstructure orderings, on phase transitions during synthesis and electrochemical cycling and on the interplay of O‐ versus TM‐redox is revealed via various advanced techniques, including semi‐simultaneous

Early math and reading achievement are associated with the error positivity

open access: yesDevelopmental Cognitive Neuroscience, 2016
Executive functioning (EF) and motivation are associated with academic achievement and error-related ERPs. The present study explores whether early academic skills predict variability in the error-related negativity (ERN) and error positivity (Pe).

Detection of Giant Pulses from the Pulsar PSR B0031-07 [PDF]

open access: yes, 2004
Giant pulses have been detected from the pulsar PSR B0031-07. A pulse with an intensity higher than the intensity of the average pulse by a factor of 50 or more is encountered approximately once per 300 observed periods.

Intramolecular Down‐ and Up‐Conversion in Dimeric Tetracene Complexes Centered via Platinum(II) and Palladium(II)

open access: yesAdvanced Functional Materials, EarlyView.
Metal‐tetracene dimeric complexes are synthesized through the pyridyl coordination to either Pt(II) or Pd(II). Photophysical properties are systematically compared as a function of the metal using steady‐state and time‐resolved spectroscopy. The Pt(II) dimer exhibits efficient intramolecular singlet fission and subsequent intramolecular up‐conversion ...

Genetic Variation of Isozyme Polyphenol Oxidase (PPO) Profiles in Different Varieties of Capsicum annuum L.

open access: yesNotulae Scientia Biologicae, 2013
The genus Capsicum commonly known as chilli pepper is a major spice crop and is of cosmopolitan in distribution. Native polyacrylamide gel electrophoresis (Native PAGE) was used to study the polyphenol oxidase (PPO) isozyme variation in 21 varieties of ...

From Low Symmetry to High Dissymmetry: Chiral Plasmonic Films of Binary and Nanobipyramid Assemblies

open access: yesAdvanced Functional Materials, EarlyView.
This work develops highly dissymmetric chiral plasmonic thin films by helically assembling gold nano bipyramids within a liquid‐crystal template. Engineering of the chiroptical response is achieved by varying particle size and geometry, as well as preparing binary assemblies.
